Practicing Taekwondo needs to move the muscles and joints of the whole body, which is a relatively comprehensive exercise. Human beings have always attached great importance to the maintenance and needs of life, so they can make appropriate adjustments in time regardless of changes in the internal environment or the external environment.

So what are the internal environment and external environment? The so-called external environment is the inseparable relationship between the human body and the outside world in order to survive. Internal environment, that is, we can understand Taekwondo as a process of survival purpose and reasonable reflection of internal and external stimuli, so as to achieve coordination, balance and unity of internal and external environment.

Taekwondo is to combine hands and feet with immovable parts of the whole body and connect them according to scientific principles. Therefore, Taekwondo has an absolute development, from the adjustment of internal and external environment to the maintenance of physical balance.

Wu Shaozu, former director of the State Sports Commission, highly summarized the functions of Taekwondo as "fitness, self-defense and self-cultivation". Since Taekwondo can become "the world's first fighting sport" and develop into an official Olympic event, it must have its own advantages and uniqueness, which will attract thousands of people from Qian Qian to participate in Taekwondo training.

(A) Fitness value

The fitness value of Taekwondo lies in that Taekwondo is conducive to students' quick thinking, improving their reaction speed, judgment and better concentration; Cultivate the excellent qualities of being diligent, studious, independent and self-reliant and persistent. Strengthening one's physique, physical coordination and flexibility is helpful to bone development and improve the level of cardiovascular function.

1. Effects of practicing Taekwondo on human muscles and blood vessels

There is no doubt that health is the most precious wealth of the human body, and it is particularly important to keep healthy.

Taekwondo is different from the sport of showing strength. It is not to build big and prominent muscles, but to turn weak adipose tissue into muscles and make the body light and agile. Normal weight-bearing exercise can make developed muscles open gaps between blood vessels. Because the number of blood vessels remains the same, it is impossible to add new blood vessels between the expanded blood vessels. In this way, the difficulty of excretion in the human body is eliminated through oxygen inhalation and blood vessels. Therefore, only by exercising unnecessary big muscles and growing tough muscles can the body get more blood and improve people's endurance, explosiveness and health.

Practicing Taekwondo is to make the muscles of upper and lower limbs stronger by kicking, twisting the waist, attacking and defending with one hand. Moreover, it exercises waist muscles by lifting and kicking, so it has a unique role in reshaping a healthy body and a balanced body shape.

2. The benefits of practicing Taekwondo to improve physical function.

Taekwondo, through scientific practice and extensive whole-body exercise, increases the pulse, increases the oxygen demand of the heart and lungs for a long time, supplies more oxygen, and makes the body tissues healthier. At the same time, it can stabilize sleep and easily eliminate excrement. In addition, practicing Taekwondo can not only make thin people gain muscle, on the contrary, it can also make obese people lose fat and return to normal weight. Taekwondo is different from ordinary sports activities. Doing strenuous activities consumes 600 calories per hour (1 calorie = 4. 18 joules), and losing weight 1 pound consumes 3500 miles. So if you practice 1 hour every day, you will lose weight 1 kg in a week.

(B) the value of self-defense

The self-defense value of Taekwondo lies in that practicing Taekwondo can temper the will and improve the unique elegant and refined temperament of practitioners. Improve self-defense ability, increase confidence, resist infringement and deal with complex social environment.

(3) Psychological value

The psychological value of practicing Taekwondo is mainly reflected in: practicing Taekwondo can reduce the pressure of life, study and work, adjust psychological balance, and maintain a good attitude to face the pressure of life, study and work.

(D) Talent value

Practicing Taekwondo can not only improve immunity, accelerate metabolism, effectively improve cardiopulmonary function and blood supply, effectively protect internal organs, and improve the body's ability to absorb nutrients from food. At the same time, we regard Taekwondo as a physical art and show our self-style through performance.

Second, the spirit and concept of Taekwondo

Learning value (1) spiritual value

Only when people have a healthy body and engage in meaningful and interesting activities can their work efficiency be the highest and their desires be the strongest. On the contrary, for a weak person, it is difficult to work efficiently, and his desire cannot be generated.

The so-called desire is a spiritual factor that can affect one's emotions before one's reason and behavior. At the same time, it is also related to a person's moral view of right and wrong, because the spiritual function of intention is not only to decide how much energy you should put into a certain job, but also to judge whether something should be done.

Taekwondo can not only affect all organs of the whole body through whole-body exercise, but also enhance people's energy, stimulate the brain, and promote their strong development, full of spirit and energy. Only in this way can we see not only a man with developed limbs and strong physique, but also a man full of vigor and creativity.

With the development of human civilization, people are no longer satisfied with living, but constantly pursuing more, stronger and broader needs, more of which are spiritual. In order to achieve this goal, people should regard sensibility and rationality as a synthesis of activities. Taekwondo exercise meets this requirement, so it is also the most effective way to improve energy and cultivate psychological quality. At the same time, Taekwondo also pays attention to a unique simple mentality in training, which depends on the magnanimous spirit of personality and strong self-confidence.

Besides, Taekwondo is also a guide to personality formation. Although man belongs to an organism, many aspects of man are inseparable from all the laws of physics. Therefore, we can also regard a series of growth, development and thinking processes of the human body as a mechanical process. The mechanical structure of this human body is a complex structure, which can adapt to various environments, adjust its shape at any time, and realize the corresponding improvement of efficiency.

On the other hand, the human body has an advanced nervous system that computers cannot replace, which makes people have psychological activities such as thinking, feeling and imagination on the spiritual level. Only in this way can spiritual development be possible. Therefore, we believe that human body and spirit are two sides of a whole, which complement each other and are indispensable. Therefore, if a person lacks proper physical training, he can't realize and produce sound thinking.

Through the study of Taekwondo etiquette and spiritual cultivation, we can treat people with courtesy, improve the level of moral cultivation, have a peaceful mind and fearless spirit, face the helplessness and confusion of life, and finally achieve the goal of carrying morality with boxing and perfecting personality.

Therefore, in the process of practicing Taekwondo for a long time, the profound cultural connotation contained in Taekwondo will be perfectly reflected in people. Taekwondo not only strengthens the body, but also focuses on influencing people's minds, cultivating people's noble sentiments and good moral character, and constantly making people paramore and pursue Excellence.

(2) Philosophical value

Taekwondo is a way to express human survival instinct consciousness with powerful body movements. At the same time, it requires people to concretize their spiritual desires, so it is a noble competitive sport. All actions of Taekwondo are based on their own defensive instinct, and then gradually become a subjective belief, from passive defensive actions to active offensive forms, and finally can reach the stage of absolute automation.

In Taekwondo, the first thing a practitioner has to overcome is not his opponent, but himself. Because a person is bold and cowardly in character, there is a difference between diligence and laziness in temperament. The former and the latter have to overcome the pain, fatigue and even the pain of injury in training. Only with perseverance can we constantly overcome our weaknesses and reach a new realm. In the competition with opponents, the offensive and defensive tactics in Taekwondo, the weight given by strength, and the initiative and passivity of morphological changes all contain contradictory opposition and unity.

In dealing with these ever-changing competitive contradictions, experience is of course important, while rational thinking and agile response can turn passivity into initiative. This is also the philosophy in Taekwondo that pays attention to making one's mind perfect, that is, although I am in my heart, I will forget myself without me. This is the philosophical value of Taekwondo.
